Slint is a toolkit to efficiently develop fluid graphical user interfaces for any display: embedded devices and desktop applications. We support multiple programming languages, such as Rust, C++, and JavaScript. Find more information at https://slint-ui.com/ or go straight to github at https://github.com/slint-ui/slint

Slint UI Library

New Features

• Add a dark mode for the fluent style (#1286)

Changes to the .slint Language

• Start working to make syntax more robust (#1734, #1754)

  This PR:

  • Adds the support for input/output/private properties #191
  • Parses the new Component declaration #1682
  • Adds some transformations in the syntax_updater to port to the new syntax
  • Introduces new lookup rules for unqualified identifier

    Instead of looking up any property in self and root, only resolve the properties in scope declared in the current component.

    CC #1750 / #273

Demos

• Add example for custom carousel widget (#1739, #1744, #1748)

  Add example with a custom carousel widget for rust, cpp and js

  Also support MCU in this example.

Tooling

• Improve property viewer widget (#1763)
  • Remove the type column from the table
  • Clicking on an defined property takes you to the property definition
  • Support grouping as supported by the new LSP (introduced in #1758)
• online editor: improve the welcome screen (#1759)
• online editor: Make document outline highlight where the cursor is (#1757)

  Make the document outline set the "active" class on the element the cursor is currently in.

  Include some css to make the browser show what is active.

• online editor: Document outline widget (#1752)

  A Document outline widget.

  It's recommended to build this on top of #1751 as without that the navigation is broken.

• Fix quality of SVG rendering in the online editor (#1740)

Fixes

• Change type of Window::background from color to brush (#1755)

  It's not a breaking change. At the moment the software renderer does not provide gradient drawing and until it is implemented a gradient window background will be drawn as solid color. Fixes #1681.

• Visit the type of array expression when collecting information on struct usage (#1743)

  Prevent compilation error in the generated code when dealing with empty array expression of a given type, which is otherwise optimized out

  Fixes #1733

• Add VecModel::extend_from_slice (#1678)

  closes #1647

  Thank you to David John for this pull request!

• Fix panic when the forward-focus expression is invalid (#1738)

  Caused a crash of the LSP when having invalid element in the forward-focus property

• Fix panic when doing binding analysis of properties in repeater in layout (#1737)

  Given an element in a layout, we must visit the properties in the repeated component, not the dummy repeated element.

  The panic is a regression since e7506e, but the missing binding loop detection was there before

• Fix type casting inside show_popup on the cpp compiler (#1735)
• Improve handling of composition events on WASM (#1746)
